"The key is what we call staying in the pocket," Obama tells David Letterman in a clip from their upcoming interview.

"I think everybody here knows dads who get out of the pocket and they're trying stuff that they can't really pull off and, you know, they start doing karate kicks and all kinds of stuff," he explained.

Obama and Letterman landed on the subject of dancing when the former commander-in-chief told a story about the time late pop icon Prince invited his daughter, Sasha, to dance with him several months before his death.
